-; a To all whom it may concern Be it known that IIHARRY L. REED, a citizenof the United States, and a resident of Dorchester, county of Sufi'olk, and Commonwealth of Massachusetts, have invented an 1 Improvement in Serum Containers and Injectors, of which the following description, in connection-with the accompanying drawings, isa specification, like characters on the drawings representing like "parts;

My invention relates to a device for storing and injecting serum, and its purpose is to provide an improved container adapted preferably to contain, in each case, a sufficient quantity of serum for one injection, and also to receive means for expelling the serum therefrom, and also to provide an improved needle for injecting the serum.

In the-drawing of the particular embodiment of my invention described and illustrated herein, Figure 1 isa sectional view of the needle, its sheath, and a container closed with the needle secured to the closure, as the container may conveniently be supplied to purchasers, the container being partly broken away; Fig. 2, a similar view with the needle sheath removed and tlie needle in position in the container for use; Fig. 3, a side view of my improved needle; Fig. 4, a vertical longitudinal section thereof on the line M, Fig. 3; Fig. 5, a view on an enlarged scale of the separate parts of the needle before assembly; Fig, 6, a similar view with the several parts of the needle assembled, and Fig. 7 a vertical section of a modified form of needle.

Referring now to'Figs. 1, 2, my container and injector is illustrated as comprising a vessel 1 of any suitable shape and material, as glass, adapted preferably to contain the proper quantity of serum for one injection. After the serum has been placed in the container its two ends are preferably normally closed air-tight at the laboratory, one end,

. see Fig. 1, being provided with a compressible needle carryingstopper or other suitable closure 2, such as rubber or cork, while the opposite end is provided with-a stopper or adapted, in any suitable manner, to re ceive a bulb 8 or other suitable means for providing pressure for forcing the serum from the container and through the needle. The needle l comprises, as'shown, Fi s. 1, 2, '3, 4, a small, slender hollow tu e .-j of suitable material as metal, commonly Specification of Letters Patent.

called the cannula, with a passage closing hub 531ntermediate its ends.

. The outer end 6 of the needle is pointedv so that it can be readily caused to pierce the skin. The needle, preferablynear or at its 1111161 end is provided with"a passage-sealing and needle-retaining section Ormember 7, and shown herein as substantially spherical. A lateral passage 8, through this member 7 connects with: the longitudinal passage 9, of the needle and thereby establishes, when the needle is in proper position, ommunication between the passage 9 and he interior of the'oontainer, see Fig. 2.

It is desirable that the container be substantially sealed after the serum, has been placed therein, and the serum protected from For this purpose the container is provided vith a suitable closure, referredto, and to provide means for conveniently carrying the needle and for readily establishing communication between the needle and container'interior, T mold or otherw1se form a narrow passage or slit 10 in the closure 2 of a size to conveniently re-;

ceive the sealing end 7 of the needle 4-, and the closure will then naturally expand and close up tightly about the needle and thus form a satisfactory, seal for the upper container end, see Fig. 1.

The hub 5 is preferably secured tothe needle at such point as will permit it to fairly enter and close the upper end of the passage 10 of the closure 2 when the spherical seal ing end 7 of the needle is pushed through the closure and into the container, see Fig. 2.

The needle, when in position in the 010s ure, may be and preferably is, after being sterilized, inclosed in a needle sheath or container 11, as of glass, the lower end 12 of which may be conveniently sealed to the neck 13 of the bottle in'any desired manner.

When the container is to be used, the

' needle sheath 11 is removed by breaking the seal between the same and the container, the needle 4 is then grasped by means of the hub 5, and the inner or spherical sealing end 7 of the needle is pushed through the passage 10 into the container, see Fig. 2. As the therethrough by means of the bulb 3 or other convenient means- Bycproviding the spherical sealing end 7 of the needle with the lateral passage 8, I findthat the passage is less likely to be choked by any small particle of the closure than is thecase Where the longitudinal passage of the needle is extended through the inner end of the needle,

- and the needle thrust through theclosure to secured to the needle in any desired manner,

establish communication with the container, the latter operation frequently resulting in the lodging in the needle passage of small particles of the closure thereby partly 'or entirely obstructing the passage; and to furto thrust the needle therethrough more easily and quickly than can be done where the stopper is solid and the inner end of the needle is sharpened to be thrust therethrough; and the enlarged sealing end of the needle acts as a satisfactory seal for the passage in the closure at its inner end as does the hub 5 at the outer end.

While the passage closing hub 5 may be I have conceived a novel and satisfactory way of so doing. Heretofore it has been common to secure a hub to a cannula by soldering it thereto. Thismethod is not only slow and expensive but the heating of the cannula during this operation weakens it.

I have conceived the idea of swaging the hub to the cannula and I am able thereby to quickly'and securely lock the parts together. For performing this step in the operation of making the needle, I provide, Fig. 5,-a generally inverted pyramidal shaped member. the opposed converging faces 14-14, of which are, however, -recessed to a considerable extent to form a relatively narrow neck 15 from which a curvilinear, substantially globular part 16 depends. This hub is first drilled longitudinally to receive the cannula snugly therein. The hub is next placed in any suitable machine and pressure applied to the substantially flat upper face 17 and the lower face 18 of the globular part 16 and the hub is compressed thereby, causing the neck 15 to collapse. inwardly and to tightly grip the cannula. The length of the hub is slightly lessened by this operation, Fig. 6,

and the diameter of the neck also slightly increased.

By means of the foregoingoperation the two members, cannula and hub forming the needle, may .be. expeditiously and efi'ectively secured at a minimum of expense.

A needlemade as described is also less expensive for the reason that itcomprises only two members. time to make needles ofthree or more parts which necessitates much expense both in the manufacture of parts and also in the cost of assembling them."

In Fig. 7 I have ilu'strated a modified form of my invention wherein the cannula, instead-of being provided with an enlarged portion at a particular point thereon only, is enlarged near the point where the hub is secured, and thus continued to its lower or inner end. This end of the cannula is pro- It is commonat this vided with one or more lateral passages 8 to connect the longitudinal passage of the cannula with the interior of the container.

The enlarged inner end, as described, by

I its more extended contact with the wall of the passage 10 through the closure 2, acts also as an effective seal for the passage and the gripping by the closure of the enlarged needle end acts to prevent the needle from being loosened in or e'xpelled from the 010- sure passage under any reasonable operating conditions".

Obviously, it is possible to modify the embodiment of my invention as described and illustrated herein in many details Without departing from the spirit thereof and within the appended claims.
